Determining an Effective Method for One-Sun-Dried Squid Drying

摘要

The research aimed to determine the effect of different drying methods including heat pump drying, hot air drying, combined infrared and heat pump drying, and combined infrared and hot air drying on the quality of one-sun-dried squid. With each method, squids are dried at three temperature degree of 40, 45 and 50°C. The quality of the product is assessed by protein content, organoleptic quality and drying rate. The research results showed that combined infrared and heat pump drying at temperature of 45°C is the most appropriate method of drying one-sun-dried squid. After drying, the protein content reaches 22/100 gram-squid; drying time is 180 minutes, the average drying rate is 3.33 %H
